Relays/Switches

A switch is a component that allows you to make and break an electrical circuit, they can be manually operated as an input to your system, or automatically triggered such as in the case of limit switches that may be switched by the motion of an actuator.

A relay is an electrically operated switch, it allows a small current such as might be found in a micro-processor I/O pin, control a larger current, such as might be needed to power a motor.
